RELATED APPLICATIONS

This application claims priority to, and the benefit of, U.S. Provisional Application No. 62/882,081 filed Aug. 2, 2019, U.S. Provisional Application No. 62/944,643 filed Dec. 6, 2019, and U.S. Provisional Application No. 62/982,935 filed Feb. 28, 2020. The contents of each of these applications are hereby incorporated by reference in their entireties.

BACKGROUND

Stimulator of Interferon Genes (STING) is a receptor in the endoplasmic reticulum that propagates innate immune sensing of cytosolic pathogen derived- and self-DNA. STING is a 378 amino acid protein, which mainly contains three structural domains: (i) N-terminal transmembrane domain (aa 1-154); (ii) central globular domain (aa 155-341); and (iii) C-terminal tail (aa 342-379). STING may form symmetrical dimers combined with its ligands in V-shaped conformation, while not completely covering the bound ligands. A STING agonist can bind into the pocket region of STING. However, the STING activation process is easily inhibited in some severe disease conditions, resulting in the inactivation of the STING pathway. Therefore, screening and designing potent STING agonists is of great importance for cancer immune therapy and other infectious diseases treatments, including, but not limited to, obesity, liver injury, sugar-lipid metabolism, and virus infection. Specific targeting of immune pathways presents opportunities for cancer therapy, potentially offering greater specificity than cell population-based therapeutic approaches.

The compounds of this disclosure modulate the activity of STING, and accordingly, may provide a beneficial therapeutic impact in treatment of diseases, disorders and/or conditions in which modulation of STING (Stimulator of Interferon Genes) is beneficial, including, but not limited to, inflammation, allergic and autoimmune diseases, infectious diseases, cancer, pre-cancerous syndromes, and as vaccine adjuvants.

The compounds of this disclosure may contain one or more asymmetric centers (also referred to as a chiral center), such as a chiral carbon, or a chiral —SO— moiety. Compounds of this disclosure comprising one or more chiral centers may be present as racemic mixtures, diastereomeric mixtures, enantiomerically enriched mixtures, diastereomerically enriched mixtures, or as enantiomerically or diastereomerically pure individual stereoisomers.

The stereochemistry of the chiral center present in compounds of this disclosure are generally represented in the compound names and/or in the chemical structures illustrated herein. Where the stereochemistry of a chiral center present in a compound of this disclosure, or in any chemical structure illustrated herein, is not specified, the structure is intended to encompass any stereoisomer and all mixtures thereof. Accordingly, the present disclosure encompasses all isomers of the compounds of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), and salts thereof, whether as individual isomers isolated such as to be substantially free of the other isomer (i.e. pure) or as mixtures (i.e. racemates and racemic mixtures). An individual isomer isolated such as to be substantially free of the other isomer (i.e. pure) may be isolated such that less than 10%, particularly less than about 1%, for example less than about 0.1% of the other isomer is present.

Individual stereoisomers of a compound of this disclosure may be resolved (or mixtures of stereoisomers may be enriched) using methods known to those skilled in the art. For example, such resolution may be carried out (1) by formation of diastereoisomeric salts, complexes or other derivatives; (2) by selective reaction with a stereoisomer-specific reagent, for example by enzymatic oxidation or reduction; or (3) by gas-liquid or liquid chromatography in a chiral environment, for example, on a chiral support such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where the desired stereoisomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired form. Alternatively, specific stereoisomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer to the other by asymmetric transformation.

The disclosure also includes various deuterated forms of the compounds of this disclosure. Each available hydrogen atom attached to a carbon atom may be independently replaced with a deuterium atom. A person of ordinary skill in the art will know how to synthesize deuterated forms of the compounds of this disclosure. For example, α-deuterated α-amino acids are commercially available or may be prepared by conventional techniques (see for example: Elemes, Y. and Ragnarsson, U. J. Chem. Soc, Perkin Trans. 1, 1996, 6, 537-40). Employing such compounds may allow for the preparation of compounds in which the hydrogen atom at a chiral center is replaced with a deuterium atom. Other commercially available deuterated starting materials may be employed in the preparation of deuterated analogs of the compounds of this disclosure (see for example: methyl-d₃-amine available from Aldrich Chemical Co., Milwaukee, Wis.), or they may be synthesized using conventional techniques employing deuterated reagents (e.g. by reduction using lithium aluminum deuteride or sodium borodeuteride or by metal-halogen exchange followed by quenching with D₂O or methanol-d₃)

Suitable pharmaceutically acceptable salts of the compounds of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), can include acid addition salts or base addition salts. For reviews of suitable pharmaceutically acceptable salts see Berge et al., J. Pharm. Sci., 66:1-19, (1977) and P. H. Stahl and C. G.

When a disclosed compound or its salt is named or depicted by structure, it is to be understood that the compound or salt, including solvates (particularly, hydrates) thereof, may exist in crystalline forms, non-crystalline forms or a mixture thereof. The compound or salt, or solvates (particularly, hydrates) thereof, may also exhibit polymorphism (i.e. the capacity to occur in different crystalline forms). These different crystalline forms are typically known as “polymorphs.” It is to be understood that the disclosure includes all polymorphs of any compound of this disclosure, e.g., all polymorphic forms of any compound named or depicted by structure herein, including any salts and/or solvates (particularly, hydrates) thereof.

Polymorphs have the same chemical composition but differ in packing, geometrical arrangement, and other descriptive properties of the crystalline solid state. Polymorphs, therefore, may have different physical properties such as shape, density, hardness, deformability, stability, and dissolution properties. Polymorphs typically exhibit different melting points, IR spectra, and X-ray powder diffraction patterns, which may be used for identification. It will be appreciated that different polymorphs may be produced, for example, by changing or adjusting the conditions used in crystallizing/recrystallizing the compound. Polymorphic forms may be characterized and differentiated using a number of conventional analytical techniques, including, but not limited to, X-ray powder diffraction (XRPD) patterns, infrared (IR) spectra, Raman spectra, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and solid state nuclear magnetic resonance (SSNMR).

The skilled artisan will appreciate that pharmaceutically acceptable solvates (particularly, hydrates) of a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), including pharmaceutically acceptable solvates of a pharmaceutically acceptable salt of a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), may be formed when solvent molecules are incorporated into the crystalline lattice during crystallization. Solvates may involve non-aqueous solvents such as ethanol, or they may involve water as the solvent that is incorporated into the crystalline lattice. Solvates wherein water is the solvent that is incorporated into the crystalline lattice are typically referred to as “hydrates.”

The present disclosure includes within its scope all possible stoichiometric and non-stoichiometric salt and/or hydrate forms.

Salts and solvates (e.g. hydrates and hydrates of salts) of the compounds of the disclosure which are suitable for use in medicine are those wherein the counterion or associated solvent is pharmaceutically acceptable. Salts having non-pharmaceutically acceptable counterions are within the scope of the present disclosure, for example, for use as intermediates in the preparation of other compounds of the disclosure.

Typically, a pharmaceutically acceptable salt may be readily prepared by using a desired acid or base as appropriate. The resultant salt may crystallize or precipitate from solution, or form by trituration, and may be recovered by filtration, or by evaporation of the solvent.

Because the compounds of this disclosure are intended for use in pharmaceutical compositions it will readily be understood that they are each preferably provided in substantially pure form, for example at least 60% pure, more suitably at least 75% pure and preferably at least 85%, especially at least 98% pure (% are on a weight for weight basis). Impure preparations of the compounds may be used for preparing the purer forms used in the pharmaceutical compositions.

The disclosure encompasses all prodrugs of the compounds of this disclosure, which upon administration to the recipient are capable of providing (directly or indirectly) a compound of this disclosure, or an active metabolite or residue thereof. Such derivatives are recognizable to those skilled in the art, without undue experimentation. Nevertheless, reference is made to the teaching of Burger's Medicinal Chemistry and Drug Discovery, 5^(th) Edition, Vol 1: Principles and Practice, which is incorporated herein by reference to the extent of teaching such derivatives.

As used herein, the terms “cancer,” “neoplasm,” and “tumor” are used interchangeably and, in either the singular or plural form, refer to cells that have undergone a malignant transformation that makes them pathological to the host organism. Primary cancer cells can be readily distinguished from non-cancerous cells by well-established techniques, particularly histological examination. The definition of a cancer cell, as used herein, includes not only a primary cancer cell, but any cell derived from a cancer cell ancestor. This includes metastasized cancer cells, and in vitro cultures and cell lines derived from cancer cells. When referring to a type of cancer that normally manifests as a solid tumor, a “clinically detectable” tumor is one that is detectable on the basis of tumor mass; e.g., by procedures such as computed tomography (CT) scan, magnetic resonance imaging (MM), X-ray, ultrasound or palpation on physical examination, and/or which is detectable because of the expression of one or more cancer-specific antigens in a sample obtainable from a patient. Tumors may be a hematopoietic (or hematologic or hematological or blood-related) cancer, for example, cancers derived from blood cells or immune cells, which may be referred to as “liquid tumors.” Specific examples of clinical conditions based on hematologic tumors include leukemias such as chronic myelocytic leukemia, acute myelocytic leukemia, chronic lymphocytic leukemia and acute lymphocytic leukemia; plasma cell malignancies such as multiple myeloma, MGUS and Waldenstrom's macroglobulinemia; lymphomas such as non-Hodgkin's lymphoma, Hodgkin's lymphoma; and the like.

As used herein “immunostimulatory agent” refers to any agent that can stimulate the immune system. As used herein immunostimulatory agents include, but are not limited to, vaccine adjuvants, such as Toll-like receptor agonists, T-cell checkpoint blockers, such as mAbs to PD-1 and CTL4 and T-cell checkpoint agonist, such as agonist mAbs to OX-40 and ICOS. As used herein “immunostimulatory agent” refers to any agent that can stimulate the immune system. As used herein immunostimulatory agents include, but are not limited to, vaccine adjuvants.

The term “Toll-like receptor” (or “TLR”) as used herein refers to a member of the Toll-like receptor family of proteins or a fragment thereof that senses a microbial product and/or initiates an adaptive immune response. In some embodiments, a TLR activates a dendritic cell (DC). Toll-like receptors (TLRs) are a family of pattern recognition receptors that were initially identified as sensors of the innate immune system that recognize microbial pathogens. TLRs recognize distinct structures in microbes, often referred to as “PAMPs” (pathogen associated molecular patterns). Ligand binding to TLRs invokes a cascade of intra-cellular signaling pathways that induce the production of factors involved in inflammation and immunity

In some embodiments the immunostimulatory agent for use in combination with the compounds of the present disclosure is a TLR4 agonist. In some embodiments, the TLR4 agonist are referred to as CRX-601 and CRX-527. Additionally, another preferred embodiment employs the TLR4 agonist CRX 547. Still other embodiments include AGPs such as CRX 602 or CRX 526 providing increased stability to AGPs having shorter secondary acyl or alkyl chains.

Thus, In some embodiments, methods of treating a human in need thereof are provided comprising administering a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), or a salt thereof and at least one immunostimulatory agent. In some embodiments, the immunostimulatory agent is a TLR4 agonist. In some embodiments, the immunostimulatory agent is an AGP. In yet another embodiment, the TLR4 agonist is selected from a compound having the formula CRX-601, CRX-527, CRX-547, CRX-602, or CRX-526. In some embodiments, the human has cancer. Also provided herein is the use a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), or a salt thereof in combination with at least one immunostimulatory agent for the treatment of a human in need thereof.

In addition to the immunostimulatory agents described above, the compositions of the present disclosure may further comprise other therapeutic agents which, because of their adjuvant nature, can act to stimulate the immune system to respond to the cancer antigens present on the inactivated tumor cell(s). Such adjuvants include, but are not limited to, lipids, liposomes, inactivated bacteria which induce innate immunity (e.g., inactivated or attenuated Listeriamonocytogenes), compositions which mediate innate immune activation via, (NOD)-like receptors (NLRs), Retinoic acid inducible gene-based (RIG)-I-like receptors (RLRs), and/or C-type lectin receptors (CLRs).

Because of their adjuvant qualities, TLR agonists are preferably used in combinations with other vaccines, adjuvants and/or immune modulators, and may be combined in various combinations.

A therapeutically “effective amount” is intended to mean that amount of a compound that, when administered to a patient in need of such treatment, is sufficient to effective treat or prevent, as defined herein. Thus, e.g., a therapeutically effective amount of a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′), or (V′), or a pharmaceutically acceptable salt thereof, is a quantity of an inventive agent that, when administered to a human in need thereof, is sufficient to modulate the activity of STING such that a disease condition which is mediated by that activity is reduced, alleviated or prevented. The amount of a given compound that will correspond to such an amount will vary depending upon factors such as the particular compound (e.g., the potency (pICso), efficacy (EC₅₀), and the biological half-life of the particular compound), disease condition and its severity, the identity (e.g., age, size and weight) of the patient in need of treatment, but can nevertheless be routinely determined by one skilled in the art. Likewise, the duration of treatment and the time period of administration (time period between dosages and the timing of the dosages, e.g., before/with/after meals) of the compound will vary according to the identity of the mammal in need of treatment (e.g., weight), the particular compound and its properties (e.g., pharmacokinetic properties), disease or disorder and its severity and the specific composition and method being used, but can nevertheless be determined by one of skill in the art.

“Treating” or “treatment” is intended to mean at least the mitigation of a disease or disorder in a patient. The methods of treatment for mitigation of a disease or disorder include the use of the compounds in this disclosure in any conventionally acceptable manner, for example for retardation, therapy or cure of a STING-mediated disease or disorder, as described hereinabove. In some embodiments, “treat” “treating” or “treatment” in reference to cancer refers to alleviating the cancer, eliminating or reducing one or more symptoms of the cancer, slowing or eliminating the progression of the cancer, and delaying the reoccurrence of the condition in a previously afflicted or diagnosed patient or subject.

“Prevent”, “preventing” or “prevention” refers to the prophylactic administration of a drug to diminish the likelihood of the onset of or to delay the onset of a disease or biological manifestation thereof. Prophylactic therapy is appropriate, for example, when a subject is considered at high risk for developing cancer, such as when a subject has a strong family history of cancer or when a subject has been exposed to a carcinogen.

The compounds of the disclosure may be administered by any suitable route of administration, including both systemic administration and topical administration. Systemic administration includes oral administration, parenteral administration, transdermal administration, rectal administration, and administration by inhalation. Parenteral administration refers to routes of administration other than enteral, transdermal, or by inhalation, and is typically by injection or infusion. Parenteral administration includes intravenous, intramuscular, and subcutaneous injection or infusion. Inhalation refers to administration into the patient's lungs whether inhaled through the mouth or through the nasal passages. Topical administration includes application to the skin.

In addition to the above described routes of administration suitable for treatment of oncology, the pharmaceutical compositions may be adapted for administration by intratumoral or peritumoral injection. The intratumorally or peritumoral injection of a compound of the present disclosure directly into or adjacent to a single solid tumor is expected to elicit an immune response that can attack and destroy cancer cells throughout the body, substantially reducing and in some cases permanently eliminating the tumor from the diseased subject. The activation of the immune system in this manner to kill tumors at a remote site is commonly known as the abscopal effect and has been demonstrated in animals with multiple therapeutic modalities. A further advantage of local or intratumoral or peritumoral administration is the ability to achieve equivalent efficacy at much lower doses, thus minimizing or eliminating adverse events that may be observed at much higher systemic doses

The compounds of the disclosure may be administered once or according to a dosing regimen wherein a number of doses are administered at varying intervals of time for a given period of time. For example, doses may be administered one, two, three, or four times per day. Doses may be administered until the desired therapeutic effect is achieved or indefinitely to maintain the desired therapeutic effect. Suitable dosing regimens for a compound of the disclosure depend on the pharmacokinetic properties of that compound, such as absorption, distribution, and half-life, which can be determined by the skilled artisan. In addition, suitable dosing regimens, including the duration such regimens are administered, for a compound of the disclosure depend on the disease or disorder being treated, the severity of the disease or disorder being treated, the age and physical condition of the patient being treated, the medical history of the patient to be treated, the nature of concurrent therapy, the desired therapeutic effect, and like factors within the knowledge and expertise of the skilled artisan. It will be further understood by such skilled artisans that suitable dosing regimens may require adjustment given an individual patient's response to the dosing regimen or over time as individual patient needs change. Total daily dosages range from 1 mg to 2000 mg, preferably, total daily dosages range from 1 mg to 250 mg.

For use in therapy, the compounds of the disclosure will be normally, but not necessarily, formulated into a pharmaceutical composition prior to administration to a patient. Accordingly, the disclosure also is directed to pharmaceutical compositions comprising a compound of the disclosure and at least one pharmaceutically acceptable excipient.

The pharmaceutical compositions of the disclosure may be prepared and packaged in bulk form or in unit dosage form. For oral application, for example, one or more tablets or capsules may be administered. A dose of the pharmaceutical composition contains at least a therapeutically effective amount of a compound of this disclosure (i.e., a compound of any one or more of Formula (I′), (IA′), (II′), (III′), (IV′) or (V′), or a salt, particularly a pharmaceutically acceptable salt, thereof). When prepared in unit dosage form, the pharmaceutical compositions may contain from 1 mg to 1000 mg of a compound of this disclosure.

As provided herein, unit dosage forms (pharmaceutical compositions) comprising from 1 mg to 1000 mg of a compound of the disclosure may be administered one, two, three, or four times per day, preferably one, two, or three times per day, and more preferably, one or two times per day, to effect treatment of a STING-mediated disease or disorder.

The pharmaceutical compositions of the disclosure typically contain one compound of the disclosure. However, in certain embodiments, the pharmaceutical compositions of the disclosure contain more than one compound of the disclosure. In addition, the pharmaceutical compositions of the disclosure may optionally further comprise one or more additional therapeutic agents, (e.g., pharmaceutically active compounds).

As used herein, “pharmaceutically acceptable excipient” refers to a pharmaceutically acceptable material, composition or vehicle involved in giving form or consistency to the pharmaceutical composition. Each excipient must be compatible with the other ingredients of the pharmaceutical composition when commingled such that interactions which would substantially reduce the efficacy of the compound of the disclosure when administered to a patient and interactions which would result in pharmaceutical compositions that are not pharmaceutically acceptable are avoided. In addition, each excipient must of course be of sufficiently high purity to render it pharmaceutically acceptable.

The compounds of the disclosure and the pharmaceutically acceptable excipient or excipients will typically be formulated into a dosage form adapted for administration to the patient by the desired route of administration. Conventional dosage forms include those adapted for (1) oral administration such as tablets, capsules, caplets, pills, troches, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets, and cachets; (2) parenteral administration such as sterile solutions, suspensions, and powders for reconstitution; (3) transdermal administration such as transdermal patches; (4) rectal administration such as suppositories; (5) inhalation such as aerosols and solutions; and (6) topical administration such as creams, ointments, lotions, solutions, pastes, sprays, foams, and gels.

Suitable pharmaceutically acceptable excipients will vary depending upon the particular dosage form chosen. In addition, suitable pharmaceutically acceptable excipients may be chosen for a particular function that they may serve in the composition. For example, certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of uniform dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of stable dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the carrying or transporting the compound or compounds of the disclosure once administered to the patient from one organ, or portion of the body, to another organ, or portion of the body. Certain pharmaceutically acceptable excipients may be chosen for their ability to enhance patient compliance.

Suitable pharmaceutically acceptable excipients include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants, glidants, granulating agents, coating agents, wetting agents, solvents, co-solvents, suspending agents, emulsifiers, sweeteners, flavoring agents, flavor masking agents, coloring agents, anti-caking agents, humectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants, and buffering agents. The skilled artisan will appreciate that certain pharmaceutically acceptable excipients may serve more than one function and may serve alternative functions depending on how much of the excipient is present in the formulation and what other ingredients are present in the formulation.

Skilled artisans possess the knowledge and skill in the art to enable them to select suitable pharmaceutically acceptable excipients in appropriate amounts for use in the disclosure. In addition, there are a number of resources that are available to the skilled artisan which describe pharmaceutically acceptable excipients and may be useful in selecting suitable pharmaceutically acceptable excipients. Examples include Remington's Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press).

In one aspect, the disclosure is directed to a solid oral dosage form such as a tablet or capsule comprising an effective amount of a compound of the disclosure and a diluent or filler. The oral solid dosage form may further comprise a disintegrant. or a lubricant.

Example 53: Activation of Human STING Signaling in THP1 Cells

THP1-Dual™ Human Monocytes cells with the homozygous HAQ allele, known to be a natural variant allele of STING occurring in 20% of the human population (Invivogen) have been engineered with two independent gene reporter systems: a secreted embryonic alkaline phosphatase (SEAP) reporter gene for NFkB activity, and secreted luciferase reporter for interferon response gene 3 (IRF3) activity were used. 4×10⁵ THP1-Dual™ cells were incubated with test Compounds in a 5-fold titration steps from 1 to 0.0128 μM in RPMI media with 10% FBS, for 24 hours at 37° C. with 5% CO₂. Cell culture supernatants (20 μl) from each incubated sample was added to resuspended QUANTI-Blue™ Solution (Invivogen, 180 μl) in each well of a flat-bottom 96-well plate, then incubated for 2 h. NFkB levels were evaluated using a spectrophotometer at 620-655 nm.

To evaluate IRF3 reporter levels, cell culture supernatant (20 μl) from each incubated sample was added to QUANTI-Luc™ assay solution (Invivogen, 50 μl), and the luminescence was measured with a SpectraMax M3 spectrophotometer (Molecular Devices).

NFkB and IRF3 reporter levels were also determined for THP1-Dual™ KI-hSTING-H232 Cells and THP1-Dual™ KI-hSTING-R232 Cells. THP1-Dual™ KI-hSTING-H232 Cells (R232H Haplotype) were generated from THP1-Dual™ KO-STING cells by knockin of the intronless coding sequence (from the ATG to TGA) of the R232H human STING variant (Invivogen). R232H has been identified as a natural variant allele of STING occurring in ˜14% of the human population. THP1-Dual™ KI-hSTING-R232 Cells (R232 Haplotype) were generated from THP1-Dual™ KO-STING cells by knockin of the intronless coding sequence (from the ATG to the TGA) of the R232 hSTING variant. Genomic studies indicate that this variant, which contains an arginine at position 232 (R232), is the most prevalent variant with an occurrence (homozygous allele) of ˜45-58% in the human population.

The EC50 value was determined from the dose response curve based on reference Compounds. Table 2a provides the results for IRF3 reporter induction THP1-Dual™ Human Monocytes cells and Table 2b provides the results for IRF3 reporter induction in THP1-Dual™ KI-hSTING-H232 Cells and THP1-Dual™ KI-hSTING-R232 Cells (“A” means <30 nM; “B” means ≥30 nM and <100 nM; “C” means ≥100 nM).
